摘要：
The invention relates to a device or pipette for extracting a particle-depleted liquid phase from a suspension, comprising: - a main flow conduit (3) for said suspension, the main conduit comprising a fractionating cell (7) comprising at least one singularity location suitable for causing the formation of at least one recirculation vortex, and a clear layer pre-configuration channel (5) positioned upstream from the fractionating cell (7), said fractionating cell (7) and said pre-configuration channel (5) are formed on a same substrate, and - at least one liquid withdrawal means (15), positioned at a region of the fractionating cell (7) where said suspension is depleted in terms of particles due to said recirculation vortex.
